MILK-CAN COVER.

, SPECIFICATION forming part of Letters Patent No. 550,021, datedNovember 19, 1895.

Application filed February 12, 1895. Serial No. 538,116. (No model.)

To @ZZ whom it may concern.-

Be it known that I, JENNY LAPLACE, a subject of the Queen of GreatBritain, residing in the city and county of San Francisco, State ofCalifornia, have invented a new' and useful Ventilated Milk-Can, ofwhich the following is a specication.

My invention relates to improvements made in milk-cans used for thetransportation of milk; and it has for its object, mainly, to provideperfect ventilation of the can, to exclude dust, flies, and insects, andat the same time prevent the contents from being thrown out.

To attain this end and object my invention consists in the describedconstruction and combination of milk-can and cover as hereinafterexplained, and pointed out in the claim, reference being had to theaccompanying drawings, that form part of this specification.

Figure l is a side view of the milk-can and its cover constructedaccording to my invention, with the cover set into the neck to close thecan. Fig. 2 is a side view of the neck and a portion of the can-body,showing the cover set for ventilation. Fig. 3 is a view of the coverseparate from the can.

In carrying out my invention I make the neck of the can longer or higherthan that on the ordinary milk-can used by the milkman, and I also givethis neck the same diameter internally from the top or rim to the bottomwhere it joins the body.

The cover for the can is constructed, as shown in Fig. 3, with a closedtop B and a cylindrical body B', the external diameter of which is thesame as the internal diameter of the neck, and the iit of the body intothe neck is so close or tight that the cover will be held and willremain in whatever position it is set in the neck, whether with greateror less extent of projection above the rim of the neck.`

In the body B are made numerous perforations or small apertures B2,beginning on a horizontal line bg, distant below the top of the coverabout one-quarter the length of the body and preferably extending allaround the circumference and down to the bottom. The top portion of thecylindrical body of the cover is thus solid or imperforate, and theremaining portion below is perforate or of such character that it allowsair to pass from the outside to the interior.

In that position of the cover in the neck when the perforated portion isset below the rim of the neck, as illustrated in Fig. l, the can istightly closed; but by drawing out the cover a greater or less distancefrom the neck more or less of the perforated portion of the cover-bodywill be exposed above the rim of the can, and through the perforationsthus exposed the air has access to the interior of the can. The coverbeing tted tightly to the neck, it will remain in any position of adjustment without being affected by the jolt or jar of the wagon duringtransportation or while being carried about on the milk-route. The coveras thus constructed is set in position by pressing it down or drawing itup in the neck by a slight movement, the can is tightly closed or it isgiven more or less ventilation, as desired, the dust or insects cannotenter the can, and the use of special means to protect the contents,such as screens or mosquito-netting commonly used, is renderedunnecessary.

Having thus fully described my invention, what I claim as new therein,and desire to secure by Letters Patent, is-

The combination with a milk-can having a long neck of the Ventilatingcover having a cylindrical body tted closely to said neck and composedof a closed or non-perforated top-portion and a perforated lowerportion, as specified.

In testimony that I claim the foregoing I have hereunto set my hand andseal.
